Chapter 8 - Development Across The Life Span Flashcards
Research design in which one participant or group of participants is studied over a long period of time.
Longitudinal design
The scientific study of the changes that occur in people as they age from conception until death.
Human development
Research design in which several different participant age groups are studied at one particular point in time.
Cross-sectional design
Research design in which participants are first studied by means of a cross-sectional design but are also followed and assessed longitudinally.
Cross-sequential design
The influence of our inherited characteristics on our personality, physical growth, intellectual growth, and social interactions.
Nature
The influence of the environment on personality, physical growth, intellectual growth, and social interactions.
Nurture
The science of inherited traits.
Genetics
Special molecule that contains the genetic material of the organism.
DNA (deoxyribonucleic acid)
Section of DNA having the same arrangement of chemical elements.
Gene
Tightly wound strand of genetic material or DNA.
Chromosome
Referring to a gene that actively controls the expression of a trait.
Dominant
Referring to a gene that only influences the expression of a trait when paired with an identical gene.
Recessive
The female sex cell, or egg.
Ovum
The union of the ovum and sperm.
Fertilization
Identical twins formed when one zygote splits into two separate masses of cells, each of which develops into a separate embryo.
Monozygotic twins
Often called fraternal twins, occurring when two individual eggs get fertilized by separate sperm, resulting in two zygotes in the uterus at the same time.
Dizygotic twins
First two weeks after fertilization, during which the zygote moves down to the uterus and begins to implant in the lining.
Germinal period
The period from 2 to 8 weeks after fertilization, during which the major organs and structures of the organism develop.
Embryonic period
Name for the developing organism from 2 to 8 weeks after fertilization.
Embryo
Times during which certain environmental influences can have an impact on the development of the infant.
Critical periods
Any factor that can cause a birth defect.
Teratogen
The time from about 8 weeks after conception until the birth of the baby.
Fetal period
Name for the developing organism from 8 weeks after fertilization to the birth of the baby.
Fetus
The development of thinking, problem solving, and memory.
Cognitive development
In this case, a mental concept formed through experiences with objects and events.

Concrete operations stage
Piaget’s last stage of cognitive development, in which the adolescent becomes capable of abstract thinking.
Formal operations stage
Process in which a more skilled learner gives help to a less skilled learner, reducing the amount of help as the less skilled learner becomes more capable.
Scaffolding
Vygotsky’s concept of the difference between what a child can do alone and what that child can do with the help of a teacher.
Zone of proximal development (ZPD)

Preconventional morality
Second level of Kohlberg’s stages of moral development in which the child’s behavior is governed by conforming to the society’s norms of behavior.
Conventional morality
Third level of Kohlberg’s stages of moral development in which the person’s behavior is governed by moral principles that have been decided on by the individual and that may be in disagreement with accepted social norms.
Postconventional morality
Stage of personality development in which the adolescent must find a consistent sense of self.
Identity versus role confusion
